Eight weeks remain in 2013-including the busy holiday travel season-but apparently Airfarewatchdog has seen enough. Last week it announced its picks for the best, and worst, U.S. airlines of the year. The top three were Frontier, Virgin America and JetBlue with United ranking last.

Yesterday, I went out to JFK Airport with no flight to catch and no visitors to greet. It was the annual Open House New York event, where private buildings and homes all over the city open to the public for a few hours, and it was a last chance to see the iconic TWA Flight Center before it is turned into a hotel. (You can see our photos from last year here.)

Native New Yorkers, retired flight attendants, tourists and architecture enthusiasts flooded the airy terminal, closed since TWA ceased operations in 2001, taking photos and sharing stories about the good old days of air travel. The mid-20th century was the high point in airport design; its airy and futuristic buildings can be appreciated by any modern day traveler who has ever had a layover at La Guardia.

We looked at some of the most iconic airport architecture in the U.S. and their current status. Is your favorite still flying?

%Slideshow-100872%DCA Terminal A – Washington D.C.’s first airport opened in 1941, and was considered to be the most modern in airport design at the time. In addition to its status as historic landmark and aviation icon, it’s also an archaeological site: the airport was built on a former colonial plantation and the birthplace of George Washington’s granddaughter.

Status: The original terminal was restored to its original look in 2004 and 2008, with the interior currently undergoing a massive renovation. You can still see many parts of the original lobby and building as it looked when President Roosevelt dedicated it. Check out some vintage postcards of the airport from the Boston Public Library.

IAD Main Terminal – One of Swedish architect Eero Saarinen’s airport designs, Dulles was designed in 1958 and dedicated in 1962, the same year the TWA terminal opened. The architect called the building and control tower “the best thing that I have done,” and inspired the design of Taiwan’s international airport. The “mobile lounges” were one of the most innovative concepts, carrying passengers in relative luxury from the terminal right to the plane

Status: Dulles wasn’t a popular airport from the beginning, as it didn’t allow jumbo jets until 1970 and the distance from the city is still off-putting, but it’s now one of the busiest in the country and is continuing to expand. The mobile lounges are still around, but the new Aero Train is more commonly used.

JFK Pan Am Worldport – The 1960 “flying saucer” was designed to bring the airplane to the passenger, sheltering the planes under the overhang for all-weather boarding. It was opened for Pan Am and renamed the Worldport in 1971 when it was expanded to accommodate the Boeing 747, and was the biggest passenger terminal in the world for several years. After Pan Am went bankrupt in the ’90s, Delta acquired the terminal and used it for many long-haul flights.

Status: Although it is on the list of the most endangered historic buildings and beloved by many airline and architecture enthusiasts, it looks like the Worldport is permanently grounded. While Delta just completed a major renovation of their other terminal at JFK, they need the room for airplane parking, and the flying saucer is already beginning to be demolished.

LAX Theme building – The distinctive Theme building is a perfect example of 1960s futuristic architecture, resembling something out of the Jetsons and actually inspiring the cartoon’s design. Part of the original ambitious plans for the airport was to connect terminal buildings with a giant glass dome, with the Theme Building serving as the main terminal, as in the picture above. One of the most famous buildings in the world, it’s photographed more than the Eiffel Tower.

Status: The Theme building has been a restaurant since 1997, and you can visit Encounter for a meal even if you aren’t flying. The free observation deck is open on weekends only if you just want to watch the planes taking off.

LGA Marine Air Terminal – For a passenger who arrives at one of La Guardia’s many dim and low-ceilinged gates, it’s hard to imagine that an Art Deco beauty is part of the same airport. Opened in 1940 and funded by the post-depression Works Progress Administration, the Marine Air Terminal originally served the glamorous Clipper planes, carrying 72 passengers on long transoceanic flights with sleeping berths and a high-end restaurant. The second World War made such flying boats obsolete, and the terminal sat unused for several decades.

Status: It’s now the main hub for Delta’s shuttle service to Boston, Chicago and Washington, even after a massive renovation to Delta’s other terminal at LGA. While it might have less modern facilities, it’s the only terminal to feature an original mural dedicated to flight (with a secret message).

LGB Main Terminal – The first trans-continental flight landed at Long Beach in 1911, but the Streamline Moderne terminal wasn’t built for another 30 years. The modernist building was considered avant garde at the time, but now feels classic and a bit romantic among airports, the kind of place you can imagine passengers boarding with hat boxes and cat eye sunglasses. Much smaller than nearby LAX, JetBlue made it a west coast hub in 2001 and put the California airport back on the map.

Status: Last year, LGB was fully modernized to make it more green and “resort-like,” with outdoor spaces outfitted with fire pits and cabanas. The renovation uncovered more of the mosaic tile art by WPA artist Grace Clements, then 28 years old, and covered by carpet for 70 years.

I recently visited the mobile website for midwest-based Sun Country Airlines, where I could check a flight status, view schedules or check my itinerary. Basically everything except what I came to do: book a flight. The confusing, unattractive, user-unfriendly design of airline websites is a common complaint of travelers, and a problem that the designers at Fi (Fantasy Interactive) have attempted to solve.

Their mock website and accompanying video highlights high-quality images, visual details such as weather temperatures, street maps and city sights, and a seamless, all-in-one-screen experience from flight booking to seat selection to flight status. Their design makes the airline more than a transportation company. It makes them a travel authority, tour guide and most importantly, a source of inspiration.

This wasn’t the first attempt at an airline website overhaul. In 2009, user interface designer Dustin Curtis published an open letter to American Airlines on his website, along with his idea of a website redesign. This was followed up by an anonymous response from one of AA’s designers, who was then fired for his message to Mr. Curtis. Funny enough, his vision of a new AA.com is pretty similar to what the airline unveiled this year with their new logo, with large images, links to deals and news and an overall streamlined look.

For something completely different, check out Anna Kovecses’ minimalist and vaguely retro design for American, along with a user-generated blog community where you might leave travel tips for frequent flyer miles.Delta relaunched its site last year with features including a travel “wallet” to store receipts to make their site more “customized” to travelers. Swedish designer Erik Linden’s gorgeous layout for a new Lufthansa site can be found online, but a visit to the German airline’s official site shows the same old crowded page. JetBlue.com has been consistently appealing and easy to use, touting the “jetting” experience rather than just a seat. Travel industry news site Skift has a nifty slideshow comparing booking sites now and from their early days. (The major innovation seems to be images over hyperlinks and text.)

One thing many of these designs have in common is suggestion and inspiration. Airlines seem to assume that most of us go to their website with a firm destination in mind, burying their route map deep in a sub-menu for us to hunt down. Yet if we are to be loyal to one brand or try to use frequent flyer miles, a map of their flights is the first destination. My husband is trying to make “million miler” status with American, and tries to book with them as much as possible, maximizing the distance and number of miles. While I can search for destinations from JFK, and even sort my number of miles, it’s harder to figure out what international destinations (such as Seoul) are served from another departure city. Shouldn’t the goal be for the airline to be one you want to return to, rather than a site you quit using out of frustration?

Remember back when JetBlue launched and everyone got excited about a low-cost carrier which would still provide a personal television screen for all of its passengers? Well, those days are officially over. Next year, JetBlue will be introducing premium seats on some of its planes, a major shift for an airline that has branded itself as a low-cost carrier.

But while running a low-cost carrier is good for marketing — travelers do love a good deal after all — JetBlue’s most recent move proves that when you’re running a big airline company, you can’t miss out on a profitable part of the market: people willing to pay extra for first class amenities. JetBlue’s new seating arrangement will attempt to do just that, offering premium paying passengers the opportunity to travel in lie-flat seats, which not only recline into 6’8″ beds, but also have a massage feature.

The premium seating is expected to debut in the spring of 2014, on its two most popular nonstop U.S. routes: New York to Los Angeles and New York to San Francisco. Not only will the premium seat allow passengers to lie down on their transcontinental flight, but they will also get a bigger television screen, coming it at a whopping 15″. Passengers lucky enough to be in rows 2 and 4 will also get their own private suite.

What will that do to prices? That remains to be seen, but in the mean time, maybe you should start saving for a good night’s sleep for next spring.

After flying with an infant to over a dozen countries and on nearly 50 flights in her 20 months, I figured I pretty much have baby travel down to a science, as much as you can call it “science” when dealing with a person who is often unpredictable and doesn’t respond to reason. While each flight gets more challenging, I’m relishing this travel time before she has opinions on where to go and what to do, and while our baggage allowance has grown, our travel style hasn’t changed much since having a baby. As her second birthday looms in July, I’m preparing for the biggest change to our travel style: having to pay full fare for her tickets as she “graduates” from infant fare. The FAA requires that all children over the age of 2 secure full fare and sit in their own seat, while babies under 2 can fly free domestically and at a fraction of the adult fare (usually 10%) internationally if they sit in a parent’s lap. So what happens if you take a trip to celebrate your child’s second birthday and they turn 2 before your return? Do you have to buy a ticket for the whole trip, just the return, or try to sneak under the wire (don’t do that)? We asked airlines for their policy on flying with a baby turning 2.

Note: These policies ONLY apply for the situation of flying with an infant under 24 months one-way and over 24 months on the return. Unless otherwise noted, a child age 2 or over for all legs of the trip will pay regular fare.Air New Zealand – Flying with the Kiwi carrier over a birthday will mean you will need to purchase a child fare (where available) for the entire journey, 75-80% of adult fare for economy tickets. Air New Zealand offers a variety of kid activities and meals, and we think the Skycouch option is perfect for young families.

American Airlines – Here’s one policy we hope new partner US Airways will honor: children turning 2 on their trip will get a free ride home with American Airlines. You will generally pay taxes and/or a portion of the adult fare for international trips, call reservations for details.

British Airways – One of the few airlines that make their policies clear on the website (they also tell you what to do when you are booking for a child who isn’t yet born!), British Airways will offer a free return for a child turning 2. More reasons to fly British: discounted child fares, families board early, you can “pool” all of your frequent flier miles on a household account, and special meals, entertainment and activity packs (ages 3 and up) are available on board for children.

Cathay Pacific – If your baby turns 2 in Hong Kong or another Cathay destination, you’ll pay a discounted child’s fare for the return only. Note that some flights might require a provided safety seat instead of your own car seat, but all flights provide infant and child meals, and “Junior VIPs” age three-six get a special activity pack.

Delta – Delta (along with partners Air France and KLM) requires you to purchase a ticket for the entire trip if your infant will turn 2 at any time before return. The good news is that on certain international routes, discounted children’s fares may be available, call reservations for details.

JetBlue – I’ve found JetBlue to be one of the most baby-friendly airlines, thanks to the free first checked bag, liberal stroller gate-check policy and early boarding for families with young children. Of course, the live TV and snacks don’t hurt either (my daughter likes the animal crackers, while I get the blue potato chips). Kids celebrating a second birthday before flying home on JetBlue will pay a one-way fare. You can book the one-way online, but should call reservations to make sure the reservation is linked to the whole family.

Lufthansa – A child fare (about 75% of adult fare) is applicable for the entire trip. The German airline is especially kid-friendly: the main website has a lot of useful information about flying with children, including how to pass time at the airport and ideas for games to play on board, and a special JetFriends kid’s club website for children and teens. On the plane, they provide baby food, snacks, and toys, a chef-designed children’s menu and special amenity kits in premium class. A nice additional extra for a parent traveling alone with a kid: Lufthansa has a family guide service to help navigate the airports in Frankfurt and Munich.

Qantas – For flights to and around down under, the child’s age at departure is used to calculate the fare, so the infant fare is honored on the return. Qantas offers meals for all young passengers, limited baby supplies and entertainment and kits on board for kids over three. On the website, kids can also download some fun activities and learn about planes.

Singapore Airlines – Good news for families flying on one of the world’s best airlines: if your child turns 2 during the journey, Singapore will provide a seat without charge. Once they graduate from infant fare, they pay 75% of adult fare. Singapore also offers a limited selection of “baby amenities,” such as diapers and bottles, and children flying on business class or higher tickets can choose from special kids’ meals.

United – A United rep declined to clarify their policy for this specific case, only emphasizing that any child 2 or older is required to purchase a seat. Assume you will pay at least one-way full-fare.

Virgin Atlantic – Virgin charges an infant fare for the whole journey, but the new 2-year-old will have their own special seat on the return. One of the world’s coolest airlines is also pretty cool for the small set, with free backpacks full of diversions (on flights from the UK), dedicated entertainment and meals.

With all the airlines above, Junior can start accruing frequent flier miles when he turns 2. Hoping to book the whole trip with miles? In general, you’ll spend the same number of miles for your child as your own seat, while lap infants traveling on miles will pay taxes and/or a fraction of the full-adult fare (this can get pretty pricey if you are flying in premium class).
